Tubes for bone nails and hollow screws

When you’re putting stainless steel material into the human body, it needs
to be ultra-pure and support the growth of vascular tissue. Our customers
include some of the world’s most demanding implant houses, who place high demands on us for their machining, sterilization, packing, stocking and delivery to world-leading hospitals.

Our tubing for bone nails and hollow screws is set apart by the high purity of our melts, which are produced in our own advanced steel mill. The tubing is characterized by its homogeneous structure, very high degree of purity and absence of delta-ferrite.

As a result, it offers high resistance to intergranular corrosion and stress corrosion cracking as well as to pitting and crevice corrosion. Significantly, our implant tubing also offers good tolerance to human tissue.
